I can echo Keith B's remarks. The KN7000 has absolutely outstanding organ registrations, both theatre and electronic.Further there are many extra organ sounds available. I have used Yamaha 9000pro for a while and the organs on that were, in a word, rubbish. I also use midi foot pedals and they are simple to install and effective..
You can't go wrong with the KN7000.
Hope this helps.
